Not installed on Firefox for Android

In Firefox non funziona più.

Funziona benissimo, mostra i prezzi passati e puoi anche decidere cosa vuoi che il grafico mostri (usato, amazon warehouse)

va de maravilla para saber la evolución histórica de los precios en Amazon

Doesn't work for Amazon Australia despite requiring that permission

muy buena

The page says no account needed, but it seems they make the extension unusable without one. I just installed the add-on, and I clicked the Keepa button while looking at a product on Amazon. Instead of getting any price history, I get a complaint that I'm not logged in. Not very helpful at all.
